Fix create-new-website bug: use correct site id.
Add columns DW1_EMAILS_OUT.TYPE, TO_GUEST/ROLE_ID.
Don't require any NotfOfPageAction when logging in by email.
Fix evolution script issues: handle emails with missing data.
Implement RdbSiteDao.changePassword(identity, new-password-hash).
Support SecureSocial login, e.g. Facebok

Add a database evolutions with DW1_IDS_OPENID columns:
LAST_NAME, FULL_NAME, AVATAR_URL, SECURESOCIAL_PROVIDER_ID,
SECURESOCIAL_USER_ID, AUTH_METHOD.

Implement e.g.:
- loginSecureSocial(loginAttempt: SecureSocialLoginAttempt)
- insertSecureSocialIdentity(..)
- updateSecureSocialIdentity(..)
- _loadIdtyDetailsAndUser(..., forSecureSocialIdentityId ...)
Make insertIdentity() work with SecureSocialIdentity

This makes createWebsite() work with Facebook login.
